IMPROVEMENT IN WHEEL-CULTIVATORS.

Specification forming part of Letters Patent No. 196,818, dated November 6, 1877; application filed June 21, 1877.

To all whom it may concern:

Be it known that I WILLIAM METTLER, of the town of Frankfort, in Will county, State of Illinois, have invented certain Improyements in Bulky-Cultivators, the description, operation, and construction of which I class of machines, to the lower part of which frame B is attached the shovels, as shown in Figs. 1 and 4.

. To enumerate the several improvements, I will proceed to speak of them in order, commencing with the device in front of the seat a on the top of the machine for steering the two front shovels, which is done by means of the bar 6, having attached at either end the rods a, fastened to the rear end of the frame 0. The operator can, by placing his feet on the cross-bar e, which is pivoted at its 'center, shift the two front shovels attached to the frame 0 by pressing alternately with his feet on either end of the cross-bar e as he rides in the seat as, being a much easier mode of mov- 1 motion of the shovel-posts.

the lever z, with its catch to engage with the hatches of the segment 12, by means of which the main frame of the machine may be raised to any height desired, or lowered to any depth practicable, and allow the machine to operate while it is so raised or lowered.

A third feature is in the use of the rear push-brace D, Fig.4, with a break-pin near the shovel. Rear braces have been used, I am aware, but not with a break-pin to give way in case the shovel strikes some obstruction. Break-pin braces have also been used in front of the shovel, but clog the shovel when used in front. By the use of this breakpin brace in the rear the shovel and its post are left free all the way up to the main frame,

so as not to clog.

Another feature consists in the use of hinged side braces a, to preventany lateral swinging The shovel-posts and the braces to are hinged to the lower part of the frame B by means of the hinge c, Fig. 5. By this arrangement, the post with its brace can swing backward in case the shovel should strike any obstruction.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:

The cross-bar e, pivoted at its center to the topof the adjustable main frame B, in'cornbination with the cross-rods a and frame 0, for the purpose of moving laterally the frame a, with its two shovels attached below, having rear push-braces with break-pins, in the manner and for the purpose set forth.

WILLIAM METTLER.
